Answer 2

Problem Analysis

We are given that 4.5 tons of watermelons were brought to two tents. The number of watermelons in the first tent is twice the number in the second tent. We need to find out how many tons of watermelons were brought to each tent.

Solution

Let's assume that the number of watermelons in the second tent is x. According to the problem, the number of watermelons in the first tent is twice that of the second tent. Therefore, the number of watermelons in the first tent is 2x.

We know that the total weight of watermelons brought to both tents is 4.5 tons. So, we can set up the following equation:

x + 2x = 4.5

Simplifying the equation:

3x = 4.5

Dividing both sides of the equation by 3:

x = 1.5

Therefore, the number of tons of watermelons brought to the second tent is 1.5 tons, and the number of tons of watermelons brought to the first tent is twice that, which is 3 tons.

Answer

The number of tons of watermelons brought to each tent is as follows: - First tent: 3 tons - Second tent: 1.5 tons
